Tired of your city-planets not being top-tier trading hubs? Then this mod is for you! This mod adds an "Ecumenopolis Commercial" colony designation that boosts the build-speed of commercial buildings and commercial arcologies by 25% and overall trade value by 20%. That is the same trade value boost as Urban Worlds, Trade Stations, and Commercial Ring Worlds.

Because Stellaris version 3.1 added a +20% trade value boost to the base Ecumenopolis colony designation, I went back to the drawing board to double down on the theme of a commercial megacity. That lead to the creation of the new "Commercial Arcology" district which provides Merchant and Clerk jobs. Choosing to use the Ecumenopolis Commercial colony designation also swaps some Clerk jobs into Merchant jobs from each Commercial Arcology, and can provide small amounts of bonus trade if you meet varying hidden, trade-related conditions - see if you can figure them out.

But wait, there's more! Empires with the Merchant Guilds civic will find that more Merchants replace Clerks. But wait, there's even more! MegaCorps replace some Clerks with Executives and Managers. And if that wasn't enough, we'll throw in positive interaction with the "Commercial Enterprise" tradition for even more Merchants, Executives, and Managers.

With the introduction of Administrative Arcologies (and Ecclesiastical Arcologies) in Stellaris version 3.3 "Libra," it is no longer possible to view Commercial Arcologies without a planetview-enhancing UI mod. See below for three recommendations.

Adds the col_ecu_trade colony type and a new district district_arcology_commercial. Overrides the col_ecu_mix colony type to match the bonuses for the default mixed ringworld (+20% immigration pull, +5% jobs output) so as to not conflict (mechanics-wise) with the new col_ecu_trade type.

Practically any mod, as long as it doesn't entirely remove ecumenopoleis or create/edit the same colony types. Compatible with Planetary Diversity.

Built for Stellaris version 3.3 "Libra." Not compatible with achievements.

In order to see and interact with the new commercial arcology district, it is necessary to use a UI mod that allows more districts to be visible. UI Overhaul Dynamic and Bigger Planet View are two possible options. If you play Stellaris on a lower resolution (such as 1366x768 or 1600x900) there are not many mod offerings that show many districts without making the planetview too large, so I created Basic Planetview: More Districts to solve that issue.

Enhanced Trade Districts and Designations to upgrade the trade-focused colony designations and districts for habitats and ringworlds.

This mod can be safely added to your savegame after the game has started. Because it adds a new district for planets, it is not advisable to remove during gameplay. Back up your savegame before trying to remove a mod.

Overwriting a colony type produces an error log. Expect to see one entry in error.log similar to this:

[00:28:40][game_singleobjectdatabase.h:147]: Object with key: col_ecu_mix already exists
